Abstract
Recently, dietetic foods containing maltitol and sorbitol have been increased, and the method of analysis for the mixture of sugars and sugar alcohols in the foods is often needed.
Authors developed the new methods for the determination of the contents of glucose, fructose, sucrose, sorbitol, maltose, mannitol, and maltitol in various foods by the gas chromatography using both of their acethyl- and trimethyl silyl-derivatives.
The method of preparation of sugar extracts from various types of foods were also studied for the analysis.
The acetylized monosaccharides and monosaccharide alcohols were separated with QF-1, the TMS-derivatives with SE-30, and the TMS-derivatives of disaccharides with OV-17, respectively.
